SELECTOR-HANDLE LOCK.

Application filed October 6, 1922. Serial N0. 592,710.

To ZZ whom t m ag/ concer/rt.'

Be it known that I, GEORGE J. NETH, a 'citizen of the United States,residing at Dayton. in the county of Montgomery and State of Ohio, 'haveinvented certain new and useful Improvements in Selectorllandle Locks,of which the following is a specifica-tion, reference being had thereinto the accompanying drawing.

My invention relates to registers having a plurality of drawers such asillustrated in my copending application No. 543,276, filed March 13.1922.

1t is the object of my invention to provide an automatic stop for theselector handle which selects a drawer to be operated.

It is a further object to provide a selector ,indicator and selectorhandle in connection with this automatic lock to lock the hand of theindicator at zero after each operation. f

It is an additional object to provide means of unlocking the lockingmechanism so that the selector handle and indicator may move to thedesired position.

Referring to the accompanying drawings: Fig. 1 is a plan view of theselector mechanism in its locked position at zero;

Fig. 2 is a plan view of the selector mechanism in its unlocked positionin position to select drawer one:

Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a section on the line 4 4 of Fig. 3, showing the details ofthe locking mechanism;

Fig. 5 is a front elevation of the unlocking plunger;

Fig. 6 is a side elevation of the unlocking plunger.

Referring to the details of the drawings. 1 is a selector plate providedwith a slot 2 and a plurality of numerals 3 arranged on either side of azero point 4. These nuA4 merals indicate the respective drawers sonumbered in the cabinet, which has a plurality of drawers. It will beobserved that these numerals are arranged on either side of the Zeropoint 4. A pointer 5 travels adjacent to each one of these numerals andwhen located opposite one of them. that particular drawer is selectedfor operation. as explained in my eopending application Serial No.5453.276, filed March 13, 1922.

The pointer 5 is mounted upon a selector which consists of a handle 6and a vertical member 7, which is carried by a lever 8. This lever 8 isconnected through suitable mechanism, which forms no part of thisinvention, to the remainder of the mechanism for unlocking therespective drawers in the cabinet. Traveling in 7 vertically is anunlockingy plunger' 10 having a head 11 and a spring 12 to retain it inits inoperative position. lhis spring 12 is carried in a cut-awayportion 13 in 7, and serves to maintain the unlocking lug 14 carried bvin its inoperative position against a shoulder 15 in 7.

Beneath the plate 1 and spaced therefrom is a second plate 16. Betweenthese plates there travels back and forth a locking plate 17 having alocking tooth 18 pro- `iecting into a cut-away portion 19in the face of7. 17 is constantly forced into engagement with 7 and into slot oropeningl 19 by a spring 20 which is mounted in a cutaway portion 21 inthe table or cabinet top upon a pin 22. One end of the spring at 23 isengaged with the cabinet top and the other end is attached as at 24 tothe locking member 17.y thus constantly forcing it into engagement withthe selectorhandle. The movement of 17 is limited by the pin 25 carriedby 1 and by 16. This pin is located in the slot 26 in 17.

It will be thus apparent that as the lever of the selector moves backand forth with its pointer, when it comes to the zero point it will belocked, and upon depressing the plunger 10 through pressure beingapplied to the button 11. the plate 17 will be moved backwardly so that18 will be pushed out of engagement with slot or opening 19 and theselector handle will be free to mow` again to another position to selectanother drawer.

In the operation of the device. when the pointer is at zero and it isdesired to open a particular drawer. the operator' presses ou the button11 to release the member 7 and moves the handle 6 until the pointer 5 isopposite the number of the drawer to be opened. whereby the member 7 andthe rod 8 attached thereto are moved to release such drawer andmechanically retained in such position until the operator opens andcloses such drawer. when the parts are automatically returned to zeroposition.

what I claim as new and desire to sec-ure fby Letters Patent, is

l. In combination,v a dial, a pointer, a

selector carrying said pointer, which travels adjacent to'l the dial, amovable locking member carried by a cabinet top to engage flocking meanson. the selector, and means carried by the selector to unlock thelocking means by moving'itout of locking po sition,
